Had my period from February 14th to February 17th. Then I had sex on February 19th and that was the last time. I haven't started my period for this cycle but I had a little bit of bleeding earlier today but it was just when I wiped. I thought it was because I was sick for a while but I'm not sick anymore. I took a pregnancy test, well two, and they were both completely negative. I don't know what exactly is going on right now...
